SHORT TERM /THROUGH SATURDAY/

Issued at 133 AM CDT Fri Oct 16 2026

Freeze warnings and frost advisories have been issued for late Friday night into Saturday morning.

Winds will gust up to 45 mph during the daylight hours Friday as the trop fold and wind max move through the area. Interestingly, the very short range models do not push the 45+ mph gusts into the area. Cloud cover will limit the amount of deep mixing but I would not be surprised if some localized gusts to 50 mph occur.

Trends with the winds will need to be watched today for a possible wind headline. The current probabilities of a wind headline is 30-35 percent.

Tonight into Saturday morning the key message is the cold temperatures. Areas roughly north of a Sterling, IL to Fairfield, IA line have at least a 50 percent probability of seeing temperatures around freezing. If the current negative delta trend on lows tonight continues, the freeze warning may need to be expanded further to the south and east. Frost is a given with winds dropping to 5 mph or less after midnight.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/

Issued at 133 AM CDT Fri Oct 16 2026

Saturday night through Thursday Assessment...medium to high (60-80%) confidence on temperatures trending above normal.

Saturday night into Sunday will be another chilly night with frost again possible but not as widespread as Friday night into Saturday. Headlines for frost may be needed.

Starting Sunday and continuing through the week a general warm-up will be seen with temperatures trending above normal for late October.

AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1222 AM CDT Fri Oct 16 2026

Winds gusting up to 26 knots with a mix of MVFR/VFR conditions will be seen through 12z/16. After 12z/16 widespread MVFR CIGS will overspread the area with isolated SHRA. Cloud cover will limit the mixing but wind gusts up to 35 knots are likely that will create considerable low level mechanical turbulence. After 00z/17 winds in time will drop to under 10 knots with clearing skies. Frost is a certainty for any non-hangared aircraft.
